NOCO Boost XL GB50 1500A 12V UltraSafe Portable Lithium Car Jump Starter, Heavy-Duty Battery Booster Power Pack, Powerbank Charger, and Jump Leads for up to 7.0L Petrol and 4.5L Diesel Engines

I bought this to primarily use with my Aprilia RSV1000... an old Italian 1000cc V-twin motorcycle renowned for starting issues in cold weather unless your battery is perfect (and I have a Noco Genius10 looking after the admittedly pretty old AGM one on this) and/or that you use the bike frequently.To be fair, this is overkill for this application given its claims to be able to crank an engine six times the size. And so it would prove. Every time I have left the bike for a couple of weeks out in the cold weather and it has refused to start under its own steam... I plug this in (using the highly recommended - if a bit expensive - Noco GBC007 cable if you also use a Noco Genius charger... but a Noco GBC002 will do if you don't) and as sure as eggs are eggs, it will start... even on those horrible 'wide open throttle' long cranking starts, this thing does the job easily. There appears to be way more than enough cranking amps available as the starter spins fast and long and the engine really doesn't have a choice but to fire.As I said, it may well be overkill for this and it's likely that the bike isn't really testing this at all... but in this application, this guarantees a started motorcycle. From fully charged, I've used it maybe a dozen times and it's still showing a green charged indicator so it's definitely not really being challenged. On a 3 litre diesel, probably a different story.Hard not to recommend it though. Easy to use. Compact. Looks the part. Starts the engine. Job done.

Great piece of equiptment. Have used it a rew times and it does the job effortlessly.

Spot on this product I’ve used it on a couple of vehicles,and started them straight away.

Excellent piece of kit and a quality product. It started my 6 litre V12 with a completely flat battery without a problem. It does take a long time to charge via the USB, depending on your connection to the mains.Note that the clamps reach 23 inches, clamp-end to clamp-end. Clearly not a problem if you are connecting direct the the battery terminals. However, if, like me, you have to connect to a remote +ve terminal and a chassis point make sure the clamps will reach as far as you need.

Hi, I have received the item in good time and good condition, however there is no plug for me to charge the buster, I have a cable which doesn't fit anything that I have, how am i supposed to charge this item.

Highly recommend, Had a problem's with a flat battery on my insignia, it started easily jump starting. nice and compact. Easy to use. Great value for money,

I was going to by the 90 model but I like overkill so I went for the XL. I'm actually quite glad I did.I read the instructions and plugged it into my USB charger. It took 4.5 hours to charge which is I think what the instructions said it would be.I have always been a bit sceptical of these little car starters because they look so small compared to the big lead acid powered ones of old. But it does do the job and it does it pretty well. I was convinced when a friend told me that his "90" model started his 5 Litre AMG Merc but all the same I wanted the extra comfort zone for my high compression 4.2 Litre Audi RS5 so I bought this bigger XL model. This model is supposed to be able to start an 8 Litre car. Three times.It does the job perfectly, however I would question its ability to do it three times in a row without charging. I think that's pushing the boundaries of belief. For example, on my 20 HP Briggs garden tractor engine, the thing was flat after three 10 second cranking sessions. But crank it it did and had the petrol been actually going into the engine <grin> it would have started. And I've no doubt that as soon as I clean out the crud from its 20 year old carburettor, it will...I also bought the optional carry case which is a nice design and this whole thing will fit nicely in my glove box until it is needed.I only have one slight complaint: The crocodile clips to connect the battery ought to be on a longer leash. On a big engine you have a big battery and opening these out to the full extent of their Y makes it a very tight stretch on my battery.

Great jump starter these, this one has enough power to start my 4.4L Range Rover.Also doubles as a battery bank too.
